Cover Story: Thermoelectric generators, which directly convert thermal energy to electricity and vice versa, have attracted a great deal of interest due to their applications in waste heat recovery and highly efficient cooling of next-generation integrated circuits. Recently, multiphase thermoelectric materials have offered higher conversion efficiencies than single-phase counterparts, providing exciting prospects to exploit the effects of secondary phases to improve the power factor and thermal conductivity of these compounds. Here, we have summarized the principal mechanisms used to enhance the conversion efficiency of these materials, including energy filtering, modulation doping, phonon scattering, and magnetic effects.
